representing like parts.

This invention relates to winding mechanism for forming yarn or thread packages, and specifically and more particularly to builder mechanism for ring spinning or twisting mechanism.

My present invention herein disclosed is intended .to provide mechanism to fulfil the same functions set forth in my co-pending application Serial No. 685,030, but the flexible element, herein a chain, is let ofi or elongated during the winding operation, and

specifically to furnish a single-acting traverse-and-gain controlling mechanism of simple form, to which existing mechanisms can be readily converted andadapted.

In order that the principle of the invention may be readily understood, I have chosen to illustrate that embodiment thereof consisting of builder mechanism for ring spinning frames, that is, a specific application of winding mechanism.

In the drawings,-Figure 1 is a front elevation of one form of builder. mechanism for ring spinning frames constituting an embodiment of the invention; F g. 2 1s a plan View of a portion thereof; Fig. 3 is aver tical transverse section of a ring spinning frame having my invention applied thereto; Fig. 4 is a detail, partially in section, of the nut or governing means for the flexible element; Fig. 5 is a sideelevation of a portion of a modified form of said mechanism; Fig. 6 is a similar view of a still further modified form thereof; and Fig. 7 is a side elevation representing a different manner of attaching the flexible element to the primary actuator lever.

In yarn orthread winding mechanism to which my invention relates, the coils of yarn are" laid along the yarn receiver by effecting a relatively oscillatory movement of a yarn guide and the yarn receiver along the latter for a portion of its length, which movement is generally called the traverse; and the package is built by shifting the path of this relative movement progressively along the axis of the yarnreceiver, which shiftingis' generally termed the gain. In the formation of such a yarn package a maximum diameter is reached at a point above the lower end thereof due to the co5perative effect of the traverse and the gain; and a portion of the package from its lower end to such point of maximum diameter is termed the base; while the conical form resulting at the other end of the yarn package is termed the chase, or the taper; and its terminus the nose of the cop.

My invention provides means whereby the package maybe wound and formed with efiiciency in a winding or spinning or twisting machine; and particularly in a spinning or twisting machine it furnishes means whereby the tension of the yarn in winding may be well controlled and thereby the lay of the yarn benefited. In the formation of the base of the package the invention provides- .means wherebythe successive layers of yarn,

may be so laid, one over the other, until the full diameter of the package is secured, that each: bottom coil of each layer is laid safely up and above the bottom coil of the preceding layer (assuming the yarn receiver to be upright and the yarn to be wound thereon from the bottom upwardas in the preferred arrangement of parts of mechanism embodying my invention) and while the mechanism accomplishes this broadly in the formation of the base of the package'it may be and in the disclosed embodiment of the invention is arranged to continue the same winding effect throughout the entire length of the package. The feature of the windmg is accomplished by increasing the gain and preferably by progressively increasing the gain throughout the formation of the base of the package; throughout the remainder of the package the gainshould besuch as to maintain the body of the package of substantially uniform diameter. To this end, I may while constantly increasing the traverse throughout the cop, so control the gain as to accomplish this result. This may be effected by providing fonan unincreased gainthroughout the body of the package abovethebase, provided the increasing traverse be maintained. Cooperatively with this mechanism for increasing the gain, mechanism is provided ito increase the traverse foo , yarn package construction of package checks the tendency the bottom coil of ceding layer. I

, a second.

. traverse andgainare age, which atthe bottom extends from the 4 surface of the-receiver to' a maximum e5 eteriwithout-laying the bottom coil of any axis of the package tends to increase,

:'face which more nearly to a flat throughout the formation of the base and preferably throughout the formation of the whole package. The result of this increase of traverse is obviously to lay each successive layer of yarn over a slightly greater extent axially of the package; and further, due to the constant speedof thespindle or other yarn receiver, and in ring frames particularly, due further to the constant speed of the feed rolls, if each traverse is effected in the same period of time (which is accomplished by giving the primary controller of the traverse movement a stroke constant in time and distance), the yarn each time will be laid in coils a little more widely separated.

Having reference to the utilization of such a yarn package which involves its funwinding features, the result is that the increasing traverse from base to nose gives reversely a decreasing taper from nose to base, so that'the yarn withdrawn by draft 1 to the axis of the package,

is in a shuttle this described of the yarn to balloon out and contact with the sides of the shuttle and therefore tends to. decrease breakage. Further, as the base of the cop is reached in the unwinding (and throughout the whole package if and when the increase in gain, is established throughout the whole package) each bottom coil of each layer (having. been safely laid 'by means of the increase in'gain over and above permitted to/be withdrawn without fouling with and tending to slough oif the pre- These advantages thus securedin the unwinding are of great practicalimportance in weaving .whcre the yarn is subjected to quick" intermittent draft reaching a speed of from five to ten yards Inasmuch. as each traverse is increased over itsfpredecessor, each traverse advances more at the'top of the wind than at therbot- .tom thereof. The effect of the described to build a yarn packdiamsurfaee at right anglesand when the .yarn package. r

the preceding layer) is.

, of the spinning wind or traverse on top of or below the bottom coil of the preceding layer or traverse. The slight but continuousincrcmental increase in the gain througiout at least the base of the package, together with'the direct increase in the traverse lays the yarn so uniformly that the base of the yarn package is formed with a straight line constituting a conical bottom in vertical cross section until the maximum diametcr of the cop or other yarn package is reached. Such maximum diameter is substantially maintained until the tip of the yarn package is reached.

Thus, the increase in traverse and incremental increase 1n gain are effective to produce and maintain a correct and advantageous form of package.

While I have referred to the increase 'in V the traverse as constant, this term 1s em ployed generically or broadly to refer to a,

preferably regular increase in the traverse, such increase occurring at a certain part of each traverse, or if desired at a certain part of each of a series of traverses. I preferably impart the increase to the traverse and the increase to the gain during the up-stroke of the ring rail and preferably near the end of such up-stroke and terminating with the end of the up-stroke. v v

Inasmuch as the buildercam employed in the disclosed embodiment .of the invention rotates preferably at a constant speed, and

inasmuch as the traverse 1S regularly increased, it follows that the speed of the ring rail is correspondingly increased, and inasmuch as the addition to the traverse and the addition to the gain are imparted in the present embodiment of; the invention at or near the end of the up-strokcjof-the ring rail, it follows that the speed of movement of the ring rail is accelerated each time toward the end of its up-stroke,that is, when the yarn is winding upon, the nose of the Referrlngmore particularly to the draw ings, and first to the, construction shown in Figs. ;1 to 4 thereof,-the frame of a winding mechanism is represented at 1. This wind- 1ng mechanism may lng yarn or thread either w1th or wlthout spinning the same. In'the present embodi ment of the invention, I have disclosed csbe employcd for windsential elements of the builder motion of a spinning or twisting. frame. .The builder cam isindicated at 2 in Fig; 3, it being fast upon a. shaIt 3 supported in the frame and driven at a preferably" constant speed, in any suitable manner, in the direction of the arrow, as from a worm'shaft driven by sprocket. gearing'from. the main drive shaft frame. Theshaft 3 may be driven at a higher rate of 'speed than heretofore without changing." the speed at which the drawing rolls and the spindles are driven v Y mana e The spindle rail is indicated at 4, the box rail at 5, both being fixedly supported on the framing 1, the spindles at 6, and the ring rail at 7, the latter preferably carrying the usual spinning rings not shown. The spindles 6 are driven by a band 8 from a drum 9 upon a shaft 10 rotated in any suitable manner. These parts are preferably of usual formation and construction, the spindles 6 being continuously rotated in one direction and the yarn being delivered there to by the usual sets of drawing rolls, not shown. I

The spindles 6 or suitable bobbins or paper or other tubes receivable thereon constitute constantly rotating yarn receivers and the ring rail constitutes one form of yarn guide traversable lengthwise of the yarn receivers.

Suitably mounted in the framingofthe machine upon a stud or pivot 11 is an actuator lever or builder lever 12 having a constant stroke imparted thereto by the builder cam 2. This builder lever is essentially a guided movable element to carry the chain, and any suitable device may be substituted therefor to accomplish the desired result. The said lever is arranged transversely of the winding or spinning frame as indicated in Fig. 3. The yarn guide or ring rail 7 is provided with a suitable number of rods or pokers 13 constituting the yarn guideholding means. Between the actuator or builder lever 12 and said yarn guide holding means I provide certain coloperating, connecting and governing devices. In the present embodiment of the invention, these devices comprise a flexible element shown as a chain 14,

governing means on upon said flexible element to move the bearing portion thereof on said lever gradually and by increments outward from the fillcrum of the lever and a second oscillating or pivoted member positively connected to said flexible element and having a sliding connection with the said yarn guide hold ing means 13. These cooperating, connectment herein shown, the let-off of the flexible element is secured by moving a traveler nut in a direction away from the bight of the flexible element where engaging the actuator lever, sothat coincidently with the letoff of saidflexible element the bearing thereof on saidrlever is moved outwardly from the fulcrumthereof to secure the desired inthe lever 12 activecrease of traverse. 3 With the flexible element attached and controlled in this manner, however, fixed incremental movement of the traveler nut will not give a progressively increasing let-off of the flexible element; and since the flexible element constitutes part of the connecting and governing devices between the actuator lever and the yarn guide holding means, and it is desired to secure a progressive advance of the latter, at least throughout the formation of the base of the package, so as to obtain a progressivelyincreasing gain, the other cooperative devices co-active with said flexible ele-.

ment to govern the movement of said yarn guide holding means are herein arranged The said nut constitutes a second bearing for the screw 17. The nut 18 constitutes one form of means that may be employed by me in carrying out my invention, to move the bight forming means toward the open part of the bight, to effect let-off of the flexible element. 1 am not limited to such disclosed form of means.

I have herein represented the flexible element or chain 14 as passing upwardly and thence about a gjniding sheave 20 rotatably supported in a racket '21 secured to some suitable part of the framing of the mecha nism. The flexible element 1% thence extends longitudinally of the framing or mechanism to the second oscillating or pivoted member to which I have referred and which is herein shown as a bell crank lever 22 mounted upon a stud or rock shaft 23 and having an arm 24 provided if desired at its outer end with a roller 25 adapted to take under the foot 25 of the yarn guide holding means 13.v The connection between the lever 22 and the yarn guide holding as I means 13 is herein disclosed as a sliding one, and may be of any suitable type involving int'ermeshing teeth if desired. The lever 22 is provided with an arm 26 to the outer end of which is connected a rod 27 extending longitudinally of the framing and connected to one or more other levers preferably generallysimilar to the lever 22 and co-acting with other yarn guiding holding means 13. The number of levers and yarn guide holding means, of course, varies with the design and structure of the mechanism.

The arm 26 of the lever 22 is provided with a curved extension 28, the flexible element receiving-surface which constitutes I a true are struck from the axis of the lever 22. The end of the chain 14 is represented as provided with ascrew eye 29 secured to the end 30 of the extension 28. The lever 22 is provided with 'a third arm 31 having In order to move thenut 18 outward upon I the actuator or builder lever'12, that is, in the direction away from the bight of the chain of the flexible element 14: passing about the sheave 19 carried by the nut 18, or, in'other'words, toward the open part of the bight of the chain, I may provideany suitable mechanism. Herein for, the purpose I have represented a ratchet 33 fast upon the outer end of the screw 17 and a sleeve 34: loosely mounted upon'the. screw '17 adjacent the ratchetand betweenit and the bearing 16, The sleeve 34 is provided with or has formed therewith a lever having an arm 35, to which is pivoted a pawl 36 taking into-the teeth of the, ratchet 33 anda, second arm 37 to which is connected by a slot and pin connection 38 a rod 39 having a threaded end 40 passing loosely through an opening in the flange 14: of a bracket 41 bolted to the box rail 5. Upon the threaded portion of the rod 39 are nuts 42, 43, and co-acting lock nuts may be provided if desired. The actuator or builder lever 11 is periodically depressed by the cam 2 and periodically rises because of the counterweight 32 upon the lever 22. Near hence rotates the screw 17 incrementallyin' the termination of eachrising movement of the lever 12, the nut 43upon the threaded rod 39 is brought into engagement with the lower face of the flange 4A of the bracket 41, and hence further upward movement of the said rod 39 is prevented. Inasmuch, however, as the, lever 12 continues its upward movement, the pawl 36 compels the clockwise rotation of theratchet 33, and

1 such .adirection as incrementally to advance the nut 18 outward along said screw 17 and the lever 12. The'extent ofv this rota- .7 tive'movement of the ratchet 33 may be varied by varying the position of the nut 43 upon the rod 39. Upon the downward movement of the lever. 12, the nut 42 bn thethreaded rod 39 contacts withthe upper face of the flange 44 ofthe bracket 41, and hence moves the pawl 36 in a contraclock-1 wise direction along the teeth of the ratchet 33; It is evident that the nut 18 is periodically moved outward along" the screw 17 at or substantially at the termination of each upward movement of the actuator lever '12,

and hence when the yarn guide 7 is substantially at the top of its traverse.

Inasmuch as the traverse is controlled by the nut 18 and inasmuch as the gain ,is controlled in part by said nut 18, it is evident, that I have in' this embodiment of the invention provided a single-acting traverse and gain controlling mechanism. In the operation of the mechanism, the traverse is increased by the gradual outward move ment of the bearing of the chain, that is, by the described movement of the nut 18, and the gain, throughout the base at least of the passage, is increased by the coiiperation of the several described instrumentalities.

In the mechanism shown in my co-pending application Serial No. 685,030 above referred to, the gain is gradually'increased by the outward movement of the bearing of i the flexible element or chain, on the builder element, and the gain is effected by the pro; gressive shortening ofthe flexible element and by the action of the said flexible element'on thesecond pivoted lever, and the action of the latter on the guide holding meanswhereby incremental rotation of the second pivoted lever is effected by the said flexible element, giving an increasing, incre- 2 mental, right line movement of the yarn guide holding means. my present invention,v howeveig'the gain,

In accordance with which is a progressively increasing gain throughoutat least the base of the yarn package, is effected, first, by progressively decrees ing'the amountof let off-of the flexibleelement or chain, instead of by a take upv of the chain'as described in my said earlier application, and second by'the cooperative action of the said flexible element 14:,the second pivoted lever 22 and the guide holding means 13,,wherebyfixed incremental'rota- 7 tion of the said second pivoted lever 22, as permitted by the said, flexible'member- '14, gives an increasing incremental advance of the guide holdingmeans to such an extent that this is dominant overthe decrease in the let ofl in the flexible element as effected by the movement of the nut 18.

During the building of the yarn or thread package, the lever'22 is not only constantly oscillated about its axis 23, but itsarcs of '12 movement constantly advance in a clockwise direction. At the commencement of the operation the arm 24 of the lever 22' y is at its lower position and the translation 7 ma clockwise direction of the 'arcs'of move ment of said lev er22 continually advances the lowermost position :of the arm 2 19f said lever until the said arm is horizontal,

at the downward limit of its are movement. This advancing movement of the arm 24 to the horizontal gives an increasing incremental advance of the guide holdingmeans. As the advance in the position'of the downward limit of'the lever arm 24 continues and rises above the horizontal, the incremental pleted. The character of the gain after the completion of the base-should be such as,

in conjunction with the described increasing traverse, to build a package, the body of-which'is of substantially uniform diameter. Throughout the base at least of the package the gain is a progressively increas-[ ing one. Within the scope of my invention the gain may be rendered a progressively increasing one throughout the entire packa e.

In that form ofthe invention shown in Figs. 1 to4, a constant rotation or advance of the lever 22 gives an increasing advance or gain up to the described horizontal position of the lever arm 24, inasmuch as the extension '28 of said lever 22 is a true are struck from the axis 23 of said lever. .By varying the shape of said extension 28, however, I may vary the character of g'ain.

. In Fig. 5, I have represented the lever 22' as having arms 24, 26. The latter is provided withan extension 45 that is not a true are struck from the axis of the lever 22, but is an are somewhat flattened along 'the part 46 thereof, so that as the lever 22 is advanced in a clockwise-direction, the amount of chain taken up thereby upon the extension 45 progressively decreases, thus ,"compensating for the decrease in the progrcssive increase of the galn that otherwlse' would occur after the arm 24 of the lever 22 had reached the horizontal as its lowermost limit of its arc movement.

In Fig. 6, I have represented alever 22 having arms 24" and 26". The latter is provided with an extension 47 that is not .wholly a true arc struck from the axis of the lever22", but is a curve, the'left hand portion 48 whereof (viewin Fig. 6) is at an increasingly greater radia distance from the axis of the lever 22" than the right hand portion thereof, which is a true are struck from said axis. As the lever 22" is advanced in a clockwise direction, the amount of chain taken up thereby from the extension. 48 progressively increases, thus somewhat further decreasing the gain after the arm 24" has reached the horizontal as the lowermost limit of its arc of movement. It is evident that by varying the curve 48, the gain may be a progressively decreasing increase of thedesired extent, or that an unincreased gain may be secured in or through J amount of chain let off for a the body of the package, or that any suitable effect may be secured, which in conjunctionwith the described increase in traverse, will result in a package of substantially uniform diameter throughout the body thereof.

In Fig, 7, I have represented further means for modifying or varying the amount of chain let cit by the movement of the nut 18 outward along the lever 12. In said fig-. ure, the nut 18 and its pulley 19 are so located that the portion of the chain 14 between the guide pulley 19 of, said nut and the guide pulley 20 upon the framing of the machine is substantially vertical when said nut 18 is at or near the inward limit of its movement along the screw 17 instead of at an acute angle as represented in Fig. 3, though suitable variation of this construction may be made. The lever 12 at its outer end is provided with a downward extension 49 having a hook 50 to which the end of the chain 14 is connected. The hook50may be secured in or at any one of the sockets or holes 51.: The lever 12 receives an oscilla- 'tory movement in the manner previously de I scribed and as the nut 18 moves outward along the screw 17, there is but very little change in the length of chain between the nut 19 and the guide pulley 20. The

amount of chain, however, between the nut 19 and the hook 50 is continually diminishi'ng, so that the resultant action may be a let-off of the chain which-effects a progressively decreasing increase in the gain. It will be observed that the hook 50 may be and is shown as so positioned that the guide pulley 19 does not movepara'llel with the portion of the chain passing around said pulley to the hook -50. Therefore the yen movement of the pulley 19 will be ecreased'as the hook 50 is approached thereby. The efl'ect ofthis is that for a. given let-ofi' of the chain necessary to give the total gain (which determines the length of the finished cop),

the pulley 19 can, if desired, be moved a greater distance, which means a greater increase 1n traverse between the beginning and ending of the building operation.

An advantage of the particular form of mechanism herein shown whereby the gain is had by a let-off of the flexible element is that itprovides-mechanism of great simlicity to which many existing forms can 0 readily converted and which will give substantially the same results in bobbins or cops'of usual lengths as is secured by the form of mechanism shown in my said earlier application, Serial No. 685,080.

Instead of employing a guiding sheave 20, I may lead the flexible element 14 directly from the actuator or builder lever 12 to a drum or disk concentrically mounted on or with the axis of the second lever 22, thus securing the same result as that disclosed in set forth in tl f -necting and governing devices onxsaid lever saidlmeans,said flex ble 'elementvoperanecting and governing bodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a: generic an descriptive sense and not for purposes of limitation, the scoperof the invention being ll-owing claims.
